在上一个提交中，引入了打开View more actions的操作，执行这个操作后，在旧代码中无法正确识别当前temporary chat状态，或是可能识别到了temporary chat状态是已打开的状态，后续发送Escape因为某些原因失败，导致View more actions这个overlay一直处于打开状态，进而无法进行其它操作如上传文件/图片、设置thinking level等

该提交执行以下修复：

1. temporary chat状态判断前置，先判断当前temporary chat状态再选择是否要打开View more actions
2. 打开菜单后，无论后续判断或操作如何，最后都执行_close_menu_if_needed()尝试关闭overlay，避免卡住其它后续操作
